[edit] Cost of prosthetic foreheads

Prosthetic foreheads do not cost $ 7. They are far more expensive.--72.20.139.135 17:31, 5 October 2006 (UTC)

But he's saving the seven dollars, to be spent at an unspecified time. Depending on the intrest rate and the time saved, the prosthetic forehead could cost any amount more than seven dollars: Cprosthetic foreheads=7(r)^t Of course, that's assuming time is measured in years and the rate is compounded annually. Let's say John puts the money in a savings account at 5% intrest compounded annually. Since this was written in 1990, it will take him until 2050 to save up the $130.75 needed for the standard-model prosthetic forehead. By then he will be 90 and will likely break his first forehead due to osteoperosis, and thus need a prosthetic one. Obviously a well thought-out plan.

This song is maybe referenced by Yo La Tengo in their song "The Story of Yo La Tango." Or maybe it's just coincidence: "And we tried, we tried with all our might/ We tore the playhouse down/ We ran headlong in our way/ We tried so hard" --wetreplies
